Be it ku n that I, RICHARD H. RICE, acitizen ofthe United. States, residing at Swampscott,' in vthe county of Essex, State of Massa- 'ehusetts1 have invented certain new and useh'ful improvements' in Packings, of which the following is a specification: My invention' relatesV to a new and useful ject to .provide apacking especially adapted for packing-the `reciprocating or other movngfibartsqo engines or the 'shafts oturbines infyiihich-superheatedsteam is used; the packing being so constructed asto be cooled by va continuous stream of water passing around it.

Wha-t l claim'as new, and'desire to secure' by Letters Patent of the United States, i s

awp

'1. In apacking-ring, th'e combination of a i 'casing which is 'provided with an openingA through' which thel device to' bepacked extends, a packing mounted -within the c asing,' a c hambenformed in the casing' which nor- I 05 mally contains cooling fluid, an integral'gwall which entirely separates 'the chamber froml the said opening, and inlet and outlet passages for conveying cooling fluid into and-out of the chamber.4

2'. Ina packing, the combination of a casingwhich is provided with an opening to receive thedevice to be packed, a packing-ring mount- -ed with-iu the casing, a uidlcontaining charnber.formed A1n the casln'gwhich is concentric,

with the opening, an integral or non-perforated wall which separates. the cl1amber-from the opening", and inlct'an'd outlet passages'for conveying cooling iuid into and out of thechamber, the.inletpass age being larger than the outlet-passage so filled at all time's.

3. In a structure of the character described,

the combination of a casing having an opening to receive thedevice to be packed,a plurality ofgrooves formed in the wall of the opening,

packing-rings mounted in the grooves, a cham ber formed 1in the casing, which is entirely separated from the packing-containing open` l ing bya thin wall, and ameans for supplying 2 5 Y cooling uid to the chamber.'

4:.; In a packing, a casing cast with a central longitudinal opening 'through which the piston 4rod or shaft passes, Ypacking-rings contained `within the opening, an annular chamthrough the casing tothe exterior thereof, as

and for the purpose specified.

'5. In a packing, a casing provided with a as to keep the .chamber t)ose specified. I i

a7. In a packing, a casing, packing-rings con# central longitudinal opening th rough which the'piston rod or shaft is adapted to pass,l

packing-rings seated in the wall of the opening, an annular chamber formed in the casing aroundthe wall and the packing-rings and vseparated 'from the shaft and the ringsby the! wall, inlet and outlet openings communicating A vwith the chamber upon "op'posite sides andV op Aposite ends, 'said openings extending through the casing to the exterior thereof, the inletopening-.being larger in diameter than the outlet-opening, as and for the-purpose specified..

6. In a packing, a longitudinally-divided casing provided, with annular grooves upon the interior, packing-rings adapted to said grooves, an annular chamber' formed 'in the casing surrounding the packing-1ngs, and inlet and outlet openings'communicating with the chamber andextendi ng through the casing to the exterior,^the inlet-opening being larger in diameter than the outlet, as and for the pur,-l

tained within thecasing, an annular chamber formed in thecasing surrounding the packingring, inlet and outlet openings extending from the chamber to the exterior of the casing, and an oil-cup provided with a pipe extending through the casing to the central bore thereof, as specied. v' n In witnesswhereo'f I have hereunto set my hand this 9th-'day of April, 1904.
